The Schedule referred `to in these Letters Patentramd making part of the sanne` To all Ill-homit may concern:

. Be itknown that I, WILLIAM G. KNOX, of Jael@` sonville, in the county of Morgen and in the 'State of I llinois, have invented certain new and useful'Improve# ments in- Grain-Separatoretnd Scourers; and do here by declare .that the following is :t full, clear, and exact descriptionthereof; reference beingshad to the accom- .pnnyingdrmvmg and tothe letters of reference marked `thereon, making n part offgthis specification.

`My presentinvention is` intended as nn improve# ment upon the grain-sconrer patented by Ine June 29,

I 1869, and consists in forming n dust-cbnmber between the cylinder and insde'perforntcd lining, and connecting said dust-chamber with the" tim-onse, so that the Adust will be carried oli` nssoon es the grain is scoured.

In order to ennble'others skilled'in the art to which myinvention' appeIta-ins Vto make and use the same, I will nowV proceed to describe its construction and operation,- 4referringHtc .the annexedthirsiwing.,`` in Fignrel is n. side elevationA of my machine; Figure 2 is n, vertical section of the cylinder, in n.- borizontnl position, showin g the dust-chamber between` u `Figure 3 is nfverti'cnlsection of the feed-bowlyslrlowing their'ielinmlbottomtherein;` A n In thisv vspecification I have not deemed it necessary to describe :my more "of the machine than what is ab-r solutely. required for a. full understanding of the pl'res'f entinveutioln 'all the-otberparts of the machine bejingfuliydescribed in my former patent.

A` represents tbe upright cylinder, through which lthe shnt't with thescourers passes'. This cylinder is the sume as. in' myfformer patent,.provided with' an inside perfornted lining or jncket, B, butin this case, said lining is placed n suitable distance from the inside of theV cylinder, so esto form a. chamber, O, :di aroundthe seme I' .Frcm near the bottom of this chamber tube, D,

-lends to the center of the fnnfcnse E, so as to draw the dust from the chamber ns it is scoured from the wheat. A 4

O'uv the opposite side f the cylinder is an air-hole, with funnel-shaped month G. y

H represents'the feed-bowl, which I have provided, innddtiou to the devices described in my former patent, with :inA inclined bottom, I, so that, when the gratin frillsV of from the cap, it will readily pass ont through theopening a.

Having thus fully described my invention, What I claim as new, and desire to secure by Leb' ters Patent, is-

The combination of tlxe`dnstcl1amber C, formed betweenthe outer cylinderA and the inner perforated '1ining,B, tube D, :md nir-inlet G, `all substantially ns and for the purposes herein set forth.
